We briefly review our modelling and numerical results for two physically relevant anisotropic problems in phase ordering dynamics, viz., phase separation of a binary mixture in the presence of a surface with a preferential attraction for one of the components of the mixture; and phase separation...

We formulate a phenomenological model for the dynamical evolution of granular mixtures in a rotating drum. In particular, we present a dynamical basis for an "effective surface tension," which penalizes sharp interfaces between regions enriched in different components of the mixture. We also...

We formulate a phenomenological model for the segregation of binary mixtures of granular materials with different roughness in a rotating drum. Our model successfully replicates a range of experimental behaviours, e.g., rapid radial segregation; slow axial segregation; and nonuniform radial...

We review our understanding of surface-directed spinodal decomposition (SDSD), i.e., the interplay of wetting and phase separation in an unstable AB mixture placed in contact with a wetting surface. In this context, we present results for two problems, viz., SDSD in a semi-infinite geometry with...

We present results from extensive numerical simulations of phase ordering dynamics in a mean-field dynamical model of weakly disordered random magnets. We apply a stringent test of dynamical scaling to confirm that the domain growth is superuniversal, i.e., the scaling function for the...

We present a phenomenological model for the dynamics of granular mixtures in a rotating drum. We demonstrate that our model successfully captures many of the experimental features known in the context of this problem. The results presented here are supplementary to those presented in a detailed...
